To all whom it may concern."

Be it known that I, BERNHARD MAI, a citizen of Germany, and a resident of Bergenfield, in the county of Bergen and State of New Jersey, "have invented certain new and useful Improvements in Fruit-stoning Apparatus, of which the following is a specification. Y

This invention relates to an apparatus by means of which plums, peaches, cherries and other fruit may be stoned in a rapid and efficient manne In the accompanying drawing, Figure 1 is a side elevation, partly in section of a fruit stoning apparatus embodying my invention; Fig. 2 a plan; Fig. 3 a detail of the slide; Fig. 4 an enlarged cross section through the plunger and Fig. 5 a detail of a modification of the plunger.

From a base plate 1 extends upwardly, the upright shaft -2 of a horizontally rotatable,

circular platform 'or carrier 3. This car rier comprises a horizontally disposed bot tom plate from the rim of which extends upwardly, at right angles a flange 4, in which are formed a plurality of fruit receiving peripheral pockets 5. Each of these pockets opens at its back into the dished central portion of the carrier by means of a radial stone emitting passage 6.

cans are provided for imparting an intermittent rotating movement to the carrier, and also for adv'ancing a plunger toward the carrier while the latter is at rest. As shown, there is fulcrumed to a bearing 7 of base plate 1, a hand lever 8, which by rod 9, is pivotally connected to a slide 10. This slide is guided along base plate 1 by straps 11, and is adapted to be projected underneath carrier 3. From the carrier there depend a plurality of pins 12, that register with the pockets 5, and are so spaced as to permit the passage of the slide between each pair of adjoining pins.

To the free end of slide 10, there is pivoted at 13, a latch 14, having a beveled rear edge. The latch is adapted to be laterally deflected by a spring 15, the play of the latch being. however, limited by a pin and slot connection 16., It will be seen that during the forward stroke of hand lever 8, slide 10 together with latch 14, will pass freely between two of the pins 12, and that as soon asthe pinsvhave been cleared, the latch will PATTET UF 1* BER-HEARD ill/[A1, 01E IBIEEGENFIELD, NEW JERSEY.

be thrown sidewise by means of its spring 15. On the return stroke of lever 8, the latch will, with its beveled edge engage one ofsaid pins (Fig.3) and thus cause carrier 3 to be turned for the distance of one space, so that in this way the desired intermittent rotary movement is obtained.

To lever 8 there is furthermore pivoted the shaft of a plunger 17, which is adapte to "open the fruit and. expel the stone.

- The plunger passes through a guide 18 and may carry a spring 19, so that it will passage .6, upon the dished body of the carrier, from which the accumulated stones may from time to time, be removed. The stoned fruit spiked upon the plunger will participate in its return movement, so as to be withdrawn from the pocket and be thence projected against a stripper 21 arranged in proximity to the plunger. This stripper pushes the fruit off the plunger, and vpermits it to fall through an openmg. 22 of plate 1 formed between carrier and stripper, into a suitable" container. (not shown).

The cutter illustrated in Figs. 1-4, is more particularly adapted for stoning peaches, plums and similar comparatively large fruit. With cherries, the plunger 23 shown in Fig. 5 should be used. This plunger is provided with a plurality of cutting blades arranged in a circle and provided with barbs 24 at their free ends. Back of the blades there is formed in the plunger, a chamber 25, having anegress opening 26. With this construction the plunger after cutting open the fruit, grasps the stone, and

It is of course, obvious that the apparatus may be adapted to be operated by power as Well as by hand.

I claim:

1. In a fruit stoning apparatus, a horizontally disposed circular carrier, comprising a bottom plate, an upwardly extending flange that joins said bottom plate at an angle, a plurality of peripheral pockets formed within said flange, a plurality of passages that connect said pockets with the central portion of the plate, combined with a bladed plunger adapted to be projected into the pockets, means, for imparting an intermittent rotary movement to the carrier, and means for reciprocating the plunger. 7

2. In a fruit stoning apparatus, a base plate, a shaft extending upwardly therefrom, a horizontally disposed circular carrier mounted on the shaft, said carrier comprising a bottom plate, an upwardly extending flange that joins said bottom plate at an angle, a plurality of peripheral pockets formed in said flange, and a plurality of passages that connect said pockets with the central portion of the carrier, a bladed plungerladapted to be projected into the pockets, a stripper mounted on the base plate, said base plate being provided with an opening intermediate carrier and stripper, means for imparting an intermittent rotary movement to the carrier, and means for reciprocating the plunger.
